Guida verificata passo dopo passo1
Recall that the maximum number of electrons in a shell is determined by the formula \$2n^2$, where $n$ is the principal quantum number (shell number).
Identify the given shell number: here, \(n = 4\).
Substitute \(n = 4\) into the formula: calculate \(2 \times (4)^2\).
Simplify the expression inside the parentheses first: \((4)^2 = 16\).
Multiply by 2 to find the maximum number of electrons: \(2 \times 16 = 32\) electrons.
